We run a dedicated server business. \
We assign ONE VLAN per customer with a 8 IP subnet (5 Usable) for the primary IP of the server + 4 IP's the customer can use.
When assigning additional IP's to our dedicated server customers... which one of the following will take more processing power from the switch as traffic and more additional IP's are assigned to servers.
Adding another subnet of 8, 16 or 32 IP's to the SAME vlan that is assigned to the customer with a "Secondary" option like so
ip address xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx secondary
to the same vlan of the customer
Doing a STATIC route to the Primary IP of the server (as the gateway) like so.
ip route xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx (server's IP)
Which one in the long run as more and more additional IP's are assigned will take up more of the switch's resources.
Thank you very much for your input
